2020 Cascadia. Are these oil spots something to be concerned about?

Hey all,

this dd15, there are multiple oil spots underneath the injector areas. also some pinkish/whitish residue near one of the large hose clamps. Is this something to be concerned about? Just wanted to get some input if anyone else out there went through the same thing because the engine runs fine, just got done running to California uphills (scary downhills), so engine did a lot of work lot of stress to it, used a lot of jake brakes as well. The only thing I did notice is that the truck increases speed slowly from 15 to 35 mph, but also it could be just in my head. Any thoughts are greatly appreciated.

 

there are 383k miles on it. I did have recent service done in December they replaced injector number 5 when the truck had 371k miles on it. I guess a diag link would come in handy. have any suggestions for an affordable one some of those can get pricy

 

thats good news becuase the problem should be easy and fast to fix. im hoping they can get me up and running by monday.
